Quality Control

Our 4-(2-Hydroxyethylamino)Phenol is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for industrial and fine chemical applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation.
